Erilda S.

I help companies transform complex, fragmented data into reliable insights by building robust data warehouse architectures, efficient ETL processes, and scalable BI solutions. With 10 years of experience in finance and business intelligence, and an academic background in economics and computer science, I bridge the gap between business requirements and technical implementation. I quickly identify what stakeholders need and translate it into stable, maintainable data solutions. How I can support your project: • Data warehouse design (facts & dimensions) • SQL development and performance optimization • ETL processes (full & delta loads) • Data quality assessment • KPI definition and calculation • BI dashboards and reporting (Power BI, Oracle BI, Tableau) I have delivered BI and analytics solutions in finance, online marketing, telecommunications, and customer analytics, including secure financial dashboards, KPI-driven reporting models, and customer journey analysis. If you are looking for a reliable and senior BI consultant who delivers clear, business-focused solutions, feel free to reach out.
